1 Claim.

This invention relates to ring spinning and ring doubling machinesoperating with either the spindle rail or the ring rail moving.

With ring spinning and ring doubling machines it is known that in thecourse of the operation for building the cop the ring rail moves up anddown, whereas the spindle rail descends only. Further arrangements existin which the cop building operation is elected While either only thering rail or the spindle rail moves. Consequently the build of the copdepends to a great deal upon the movement of either the ring rail or thespindle rail or of both said rails respectively.

If the movements of these rails are swerving the uniform build of thecop is impaired. On the other hand care must be taken that the relativeposition of the spindle rail and the ring rail remains unaltered in thehorizontal direction. In any event all the spindles must beconcentrically arranged with the associated spinning rings at all timesin spite of the rails moving in the vertical direction. Also the partsfor moving the spindle and ring rails must be suitable for use inspinning mills by being extremely simple and strong.

With a View to satisfying these requirements it is indispensable thatprecise movement for the rails is ensured by means of strong guides. Asguide members mostly round rods or tubes are used which are rigidlyconnected with the movable rails or are secured to the intermediateshields of the machine frame.

This simple construction has the drawback that in the guide bores whichfor the reasons mentioned above must be provided with only a slightamount of clearance, dust, fluff or other foreign matter is likely toaccumulate, thereby inviting jamming or even seizing (stoppage) of themovable rail. Apart from this the slight amount of clearance allowablefor the guide bores requires perfect parallelism between the guide rodsin consequence of which the construction of the machine is considerablycomplicated. Due to the fact that the floors of spinning mills areusually susceptible to changing their original form by extraneousinfluences, frequent jamming is liable to occur in the machine, wherebythe movement of parts may be stopped and eventual deformations of therails may ensue. The drawbacks referred to are also present to a like orsimilar extent in slot guides cooperating with guide pins.

In order to eliminate the drawbacks referred to in ring spinning andring doubling machines operating with either the spindle rail or thering rail moving, according to this invention `the movable rail isdisplaceable by means of open slide guides which are arranged on themachine frame and against which the rail bears by the action of its ownweight.

By this means the movable rail is associated with an open, that is, abed-like exposed guideway positively preventing jamming or seizing ofthe rail. In this arrangement the movable rail is adapted to evadeobstructions that may block the sliding surfaces by lateral shiftingmovement without deviating from horizontal position. Furthermore, fluff,dust or other foreign particles (even such that are hard to remove) areprevented from adhering due to the fact that the rail bears against thesliding surfaces without play, so that these surfaces are automaticallycleaned during each throw of the rail. Moreover, the arrangementaccording to the invention has the advantage that the guide-ways of therail are not influenced to any great extent by deformations of the flooron which the machine is mounted.

In the accompanying drawing an embodiment of the invention isillustrated by way of example only, in which Fig. 1 shows an elevationof this embodiment;

Fig. 2 is a cross-section thereof, and

Fig. 3 is ahorizontal section lon the line III--III in Fig. 1.

Only the parts necessary for explaining the invention are shown in thedrawing.

The numeral I designates the spindle rail or the ring rail, as the casemay be, the rail being provided with two longitudinal parts rigidlyconnected to each other by cross-pieces 2. Each cross-piece 2 isprovided adjacent to each end thereof with a laterally extending boredprojection 3 for engagement with one end of a flexible suspension member4, for example a rope. Each suspension member 4 passes over a sheave 5and is connected at its second end with a control member 5. Thecross-pieces 2 cooperate at their end with open slide guides 6 laterallyarranged on connecting Webs or partition walls 1.

The sheaves 5 are so located relative to the points of attachment formedon the rail l by the bored projections 3 that the suspension members 4extend upwardly somewhat oif of the vertical, in such manner, that therail l bears against the sliding surfaces 6 by means of the cross-pieces2 by action of its own weight and is thus longitudinally guided. Therail is further presented a second sliding surface which is formed bythe edges of the partition walls 1 and extends perpendicularly to theexposed sliding surface 6 cooperating with the respective longitudinalpart of the rail, so that the rail is guided in the transverse directionalso.

What I claim is:

Ring spinning and ring twisting machine comprising a frame formed withopen slide guides, rails mounted for movement during the working of themachine along said slide guides on the frame, obliquely disposed railsupporting members, support rollers, said rails being forced againstsaid guides by the oblique pull transmitted by said support membersthrough the agency of said support rollers by a component of the weightof the structure per se.
